Rhythm. Normal cardiac rhythm arises from the SA node (sinus rhythm) but pacemaker impulses can come from ectopic foci in the atria, the AV junction, and the ventricles under abnormal conditions. When an ectopic impulse occurs singly, it generates a beat; when the beat repeats itself, it becomes a rhythm.
The Ksp value is calculated from the concentrations of the products of Ca(OH)2 when the compound is added to an aqueous solution. Calculating the value requires knowing those concentrations, the...

Ksp Problems â Chemistry Name: _____ 1) The value of Ksp of AgCl is 1.8 x 10-10. What would be the molar concentration of Ag+ and Cl-in pure water placed in contact with solid AgCl(s)? Ksp = [Ag +] [ Cl-] 1.8 x 10-10 = [x] [x] x = 0.000013416 M or 1.3416 x 10-5 M 2) The molar solubility of PbCl 2
